Description

Footbridge and construction method thereof

The present invention relates to a footbridge and its construction method, and more particularly, to a footbridge and its construction method, which are easily installed on the shore or at the edge of a river or across a river so that pedestrians or bicycles can pass.

Recently, bicycle roads can be constructed on national and local roads so that safe and convenient roads can be constructed while efficiently satisfying traffic demand in terms of quality and quantity, and road access to tourist attractions and roads in urban areas. The Act on the Promotion of Bicycle Use has been enacted and implemented with the purpose of encouraging the construction of bicycle paths on roads with heavy bicycle traffic, such as promoting the safety and convenience of bicycle users, and contributing to the vitalization of bicycle use.

In addition, in recent years, in order to reduce the use of vehicles and increase the use rate of bicycles due to rising oil prices and environmental pollution, active policy establishment and support are being conducted at the national level. For example, in addition to the sidewalks of general roads, new bicycle paths are being built in parks and riversides.

Such a bicycle road is usually constructed by modifying a part of an existing road or sidewalk, but in this case, the bicycle road has no choice but to encroach on a part of the existing road or sidewalk, resulting in many complaints due to user inconvenience on the road or sidewalk. did.

Therefore, in recent years, in order to solve this problem, there is a demand for a footbridge that crosses a river and does not encroach on a part of an existing road or sidewalk.
